Assessment of genetic disturbance via hybridization in marine fishes by artificially introduced exotic populations

利用线粒体DNA和微卫星DNA标记对日本近海温带鲈鱼（Lateolabrax japonicus）杂交造成的遗传干扰进行了评价。在高知县采集的若干标本被推断为日本本土温带鲈鱼与人工引进的中国温带鲈鱼的杂交品种，表明了非本土种子在海洋养殖中的风险。在引入非本地种子之前，评估本地和非本地种群之间的遗传异质性和评估杂交的可能性是可取的。

Genetic disturbance via hybridization in Japanese temperate bass Lateolabrax japonicus around Japanese coastal waters was assessed using mitochondrial DNA and microsatellite DNA markers. Several specimens collected in Kochi Prefecture were inferred as hybrid between native Japanese temperate bass and artificially introduced Chinese temperate bass, indicating the risk of non-native seed in marine aquaculture. The assessment of genetic heterogeneity between native and non-native populations and the evaluation of the possibility of hybridization prior to introducing non-native seed are desirable.
